We also know that on this side of the ocean. Successful movies get a sequel, successful tv series get a movie (downtown abbey the movie

)
One of the most remarkable, here in the Netherlands, we had a movie which was a big success. And then they announced a tv series. The movie was 120 minutes. The tv series 180 minutes. And I had hoped the series would be completely new, "what happened before/after the movie takes place". Nope, the series was basically the extended cut, with all the deleted scenes.
